Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March
11, 2011, TEPCO's facilities including our nuclear power stations have
been severely damaged. We deeply apologize for the anxiety and
inconvenience caused.
With regard to the accident at Fukushima Daiichi Nuclear Power Station, on
April 17, we have compiled the roadmap towards restoration from the
accident and then we updated the progress status of roadmap considering
the current situation, on July 19. Accomplishment of the Step1 target
"Radiation dose is in steady decline" has been confirmed. On August 17, we
updated the further progress.
By bringing the reactors and spent fuel pools to a stable cooling
condition and mitigating the release of radioactive materials, we will
make every effort to enable evacuees to return to their homes and for all
citizens to be able to secure a sound life.
Below is the status of TEPCO's major facilities.
*Updates are underlined.
[Nuclear Power Station]
-Fukushima Daiichi Nuclear Power Station:
Units 1 to 3: shutdown due to the earthquake
(Units 4 to 6: outage due to regular inspections)
*At 10:00 am on September 7, we started transferring accumulated water at
Unit 2 condenser to the basement of Unit 2 turbine building. At 4:07 pm
on the same day, we stopped transfer.
*At 10:19 am on September 7, we started transferring accumulated water
from Site bunker building to Process main building at Centralized
Radiation Waste Treatment Facility. At 4:01 pm on the same day, we
stopped transfer.
*On September 8, a worker of co-operating company forgot to bring the full-
face mask when that worker commuted from J-Village to Fukushima Daiichi
Nuclear Power Station. At 5:55 am, when the worker entered the Main Anti-
Earthquake Building, it was found out that the worker did not wear the
full-face mask. We evaluated the internal exposure dose of the worker and
confirmed that the level was insignificant to cause bodily influence.
-Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to the earthquake
-Kashiwazaki Kariwa Nuclear Power Station:
Units 5, 6: under normal operation
(Units 1 to 4 and 7: outage due to regular inspections)
[Thermal Power Station]
-Power supply has returned to normal and facilities damaged by the
earthquake are now being handled in a timely manner.
[Hydro Power Station]
-Power supply has returned to normal and facilities damaged by the
earthquake are now being handled in a timely manner.
[Impacts on Transmission Facilities]
-Power supply has returned to normal and facilities damaged by the
earthquake are now being handled in a timely manner.
[Perspective of Power Supply and Demand Balance in this Summer]
-In September, we forecast the maximum supply will be 55.6 GW, and the
assumed peak demand 46.06 GW.
We apologize for the inconvenience this may cause and appreciate for your
cooperation to save electricity.
